      load_map_projection(filename) yields the map projection indicated by the given file name. Map
        projections define the parameters of a projection to the 2D cortical surface via a
        registartion name and projection parameters.
  
      This function is primarily a wrapper around the MapProjection.load() function; for information
      about options, see MapProjection.load.
